Inline Check Valves

DRV DIRECT ACTINGRELIEF VALVESC Hydraulic Engineering direct acting relief valves are available in 1/4” NPT and9/16-18 60° cone high pressure fitting for relieving pressures from 100 to 60,000 psi.The stainless steel construction makes these valves suitable for hydraulicfluids, water and gas applications. Standard seal material is Buna-N (-N).Substitute a “-V” for Viton ® or “-E” for EPR after the part number for theseseals. Specify “-V” seals for gas applications.RETURN2XPRESSURETYPE ARETURNPRESSURETYPE BModel No.DRV-010-N-025TypeAAdjustmentRange100 to 1,000psigDIRECT ACTING RELIEF VALVEConnection PortsInlet2ea1/4" NPTTank1/4" NPTServiceGas **Liquid"L" Dim.Inch"A" Dim.Inch"B" Dim.Inch"D" Dim.Inch7.31 Max 1.84 1.73 1.50 ØDRV-050-N-025A500 to 5,000psig2ea1/4" NPT1/4" NPTGas **Liquid7.31 Max 1.84 1.73 1.50 ØDRV-100-N-025A1,000 to10,000 psig2ea1/4" NPT1/4" NPTGas **Liquid7.85 Max 1.84 1.73 1.50 ØDRV-200-N-HF4B5,000 to20,000 psig9/16-18HF4*9/16-18HF4*Gas **Liquid8.79 Max 1.76 2.02 2.00 ØDRV-300-N-HF4B10,000 to30,000 psig9/16-18HF4*9/16-18HF4*Liquid 8.79 Max 1.76 2.02 2.00 ØDRV-600-N-HF4B10,000 to60,000 psig9/16-18HF4*9/16-18HF4*Liquid 8.79 Max 1.76 2.02 2.00 Ø* for 1/4 O.D. coned & threaded 30K & 60K psi tubing ** Use Viton seals for gas applications
